As the shaft C rotates, the water in the lubricating system will by centrifugal action be impelled outwardly to the walls of the pipe sections 23, and the lubricant will occupy the space next to the shaft C.

The ducts 25 through the bearing 10aL and the ducts lOf through the bearings l0 provide circulation passages in addition to the ducts 24 and 10e. Such lubricant as accumulates at the top of the conducting means will tend to rise into the receptacle G as the pipe 21 and arranged to provide a proper path for the lubricant ascending to the receptacle.

It is manifest that many variations in provision, construction, formation and interrelation of parts, members and features may be made, in departure from the specific disclosure of the foregoing description and the drawings, without departing from the spirit of the invention or a fair interpretation thereof.

Having thus disclosed my invention, I claim and desire to secure by Letters Patent:

1. In a lubricating system, a submerged shaft, lubricant conducting means open at one end to the liquid in which the shaft is submerged and adapted to confine lubricant introduced therein to a path of travel which includes a plurality of bearings for the shaft adapted to be successively traversed by the lubricant, and means for introducing lubricant into said conducting means; said lubricant conducting means including said bearings.

2. In a lubricating system, a submerged shaft, lubricant conducting means adapted to contain lubricant and a liquid of greater specific gravity than the lubricant and through which the lubricant will rise and traverse a bearing when introduced into said liquid below the bearing, and means for so introducing the lubricant; said lubricant conducting means including said bearing.

3. In a lubricating system, a vsubmerged shaft, lubricant conducting means communicating-at its lower end with the liquid in which the shaft. is submerged and adapted to contain a body of such liquid through which the lubricant may rise and successively traverse a plurality of bearing for the shaft when the lubricant is introduced into said body of liquid below the bearings, and means for so introducing the lubricant; said lubricant conducting means including said bearings. i

6. In a lubricating system for the operating shaft of submerged apparatus, said shaft a lubricant conducting means in which the shaft lies in part and whichy is adapted to receive and contain liquid from the body of liquid, in which the apparatus is submerged and adapted to receive lubricant at the lower portion thereof and in which rotary motion is imparted by the shaft to the liquid and lubricant so received to cause the seperation thereof by centrifugal action as the lubricant rises through the liquid, and pressure means for supplying the lubricant; said lubricant conducting means including a bearing for said shaft.

7. In a lubricating system for the operating shaft of submerged apparatus, said shaft, a lubricant conducting meansin which the shaftlies in part and which is adapted to receive and contain liquid from the body of liquid in which the apparatus is submerged and adapted to receive lubricant at the lower portion thereof and in which rotary motion is imparted by the shaft to the liquid and lubricant so received to cause the. separation thereof by centrifugal action as the lubricant rises through the liquid, a lubricant receptacle connected with the upper end of said conducting means, and pres-
